ACCESSORIES ACCESSORIES
Miscelatore stereofonico passivo (non alimentato) con 4 canali di ingresso e 2 canali di uscita studiato
per sistemi multivia attivi OEM dove ciascun altoparlante viene alimentato da uno specico canale
amplicato. SPM4 effettua la miscelazione attraverso 4 trasformatori audio appositamente studiati per
avere una bassissima distorsione e una elevata linearità.
SPM4 permette di miscelare i canali del midrange/woofer e del tweeter che provengono dall’amplicatore
e fornire un unico canale medio-alto. I canali Ch1(L/R) hanno due ingressi di cui uno invertente rispetto ai
canali Ch2 (L/R); frequentemente la miscelazione dà migliori risultati sfasando di 180° uno dei due canali.
SPM4 è particolarmente indicato per estendere il numero degli ingressi dei processori digitali o
amplicatori con DSP Audison in quanto dotati di de-equalizzatore (De-Eq). In questo caso le eventuali
non linearità dovute alla miscelazione dei canali ltrati preesistenti vengono debitamente compensate.
Stereo passive mixer (unpowered) featuring 4 input channels and 2 output channels, designed for active
OEM multi-way systems where each speaker is powered by one specic amplied channel. SPM4 mixes
audio through 4 audio transformers specically developed to achieve very low distortion and highly linear
acoustic response. SPM4 provides the ability to mix the midrange/woofer and tweeter channels coming
from the amplier and supply one single mid-high channel. The Ch1(L/R) channels feature two inputs,
one features an inverting input compared to Ch2 (L/R) channels; the mixing process often gives better
results when one of the two channels undergoes a 180° dephasing. SPM4 is especially recommended
to extend the number of inputs of the Audison digital processors or ampliers with built-in DSP because
they feature a De-equalizer (De-Eq). In that case, any possible non-linear acoustic emissions due to the
mixing of the pre-existing ltered channels are duly compensated.

*ATTENZIONE: Si consiglia di provare ad utilizzare i canali Ch1(L/R) con ingresso invertente rispetto
ai canali Ch2 perchè nella maggior parte delle applicazioni si hanno migliori risultati.
*WARNING: We suggest that you try using the Ch1(L/R) channels featuring inverting input compared
to the Ch2 channels , because with most applications better results are achieved.

*ATTENZIONE: i processori Audison bit (bit One, bit Ten, AP bit),
utilizzano i canali 1 e 2 per la rilevazione dell’Auto Turn On
(ART). Inserendo l’ SPM4, la funzione ART non sarà più attiva;
utilizzare quindi i canali 1 e 2 dei processori Audison bit
sui
canali d’uscita Hi Level della sorgente non connessi all’SPM4.
*WARNING: the Audison bit processors (bit One, bit Ten, AP bit), use
channels 1 and 2 to detect the Auto Turn On (ART). By
mounting SPM4, the ART function will be disabled; so, use
channels 1 and 2 of the Audison bit processors on the head
unit Hi Level output channels that are not connected to SPM4.
